Arch Day 1 Recap

What is the maximum file size allowed to upload into an S3 bucket?

A solutions architect wants to design a solution to save costs for Amazon EC2 instances that do not need to run during a 2-week company shutdown. The applications running on the instances store data in instance memory (RAM) that must be present when the instances resume operation. Which approach should the solutions architect recommend to shut down and resume the instances?

• Modify the application to store the data on instance store volumes. Reattach the volumes while restarting them.

• Snapshot the instances before stopping them. Restore the snapshot after restarting the instances.

• Run the applications on instances enabled for hibernation. Hibernate the instances before the shutdown.

• Note the Availability Zone for each instance before stopping it. Restart the instances in the same Availability Zones after the shutdown.

Your company is planning to store sensitive documents in a S3 bucket. They want to keep the documents as private but serve content only to selected users based on a particular time frame. Which of the following can help you accomplish this?

• Enable CORS for the S3 bucket

• Use KMS and enable encryption for the files

• Create pre-signed URL’s

• Enable versioning for the S3 bucket

A company has an application that needs to be hosted on an EC2 Instance. The general amount of throughput data per volume will be in the range of 400-500 MiB/s from the application. Which of the following should be used as the storage type for the underlying EC2 Instance in a Cost-effective manner?

• EBS - General Purpose SSD

• EBS - Provisioned IOPS SSD

• EBS - Throughput Optimized HDD

• EBS - Cold HDD

A company needs to maintain access logs for a minimum of 5 years due to regulatory requirements. The data is rarely accessed once stored, but must be accessible with one day’s notice if it is needed. What is the MOST cost-effective data storage solution that meets these requirements?

• Store the data in Amazon S3 Glacier Deep Archive storage and delete the objects after 5 years using a lifecycle rule.

• Store the data in Amazon S3 Standard storage and transition to Amazon S3 Glacier after 30 days using a lifecycle rule.

• Store the data in logs using Amazon CloudWatch Logs and set the retention period to 5 years.

• Store the data in Amazon S3 Standard-Infrequent Access (S3 Standard-IA) storage and delete the objects after 5 years using a lifecycle rule.
